S ummary A simple polarographic device is described which permits the measurement, in the gas‐phase, of O 2 evolved by leaf discs during photosynthesis and O 2 consumed in respiration. A method of calibration is described and results are included which illustrate the performance of the apparatus in typical experiments.
